[0003] According to the structure of the scale body, the scales can be divided into: I-beam scales, T-beam scales, L-beam steel scales, U-shaped steel scales, channel steel scales, and reinforced concrete scales; according to the type of sensor, they can be divided into digital scales and analog scales.

[0004] The existing scale steel structure carrier is not easy to rotate. Therefore, in the Chinese utility model patent with the patent number CN201922409423.X, the name is a mobile small scale steel structure carrier (such as Figure 1 As shown in the figure, by setting a support plate, a first connecting plate, a first electric push rod, a second connecting plate, a groove, a rolling bearing, a first rotating shaft, an annular connecting block, an annular groove, a connecting rod, a first universal wheel, a second electric push rod, an electromagnet, an annular rack, a motor, a second rotating shaft and a gear, the direction of the carrier body can be quickly rotated. However, the support legs on the existing floor scale are directly supported on the ground by the second universal wheel. When the load is on the floor scale, the load directly acts on the second universal wheel. If the second universal wheel is under load for a long time, it will cause damage to the second universal wheel, which is not conducive to the movement of the floor scale. The existing floor scale has many device structures for rotation. During routine maintenance, it is necessary to prepare multiple spare parts according to the structure, which greatly increases the cost of equipment maintenance and increases the difficulty of maintenance for maintenance personnel.

[0032] In this embodiment, combined with Figure 6 As shown, the rotating mechanism of this embodiment includes a motor base 9 and a rotating base 10. The rotating base 10 is welded to the middle of the bottom of the carrier body 8. A bearing 17 is installed between the bottom of the rotating base 10 and the top of the motor base 9. An explosion-proof motor 15 for rotating the rotating base 10 is installed in the motor base 9.

[0033] In this embodiment, combined with Figure 6 As shown, the support mechanism is installed at the bottom of the electrode seat and is used to support the motor seat 9.

[0034] Specifically, when the small scale steel structure carrier provided by this embodiment is used to rotate the carrier body 8, refer to the following principles.

[0035] The carrier body 8 is supported by a supporting mechanism, and the rotating mechanism is installed between the carrier body 8 and the supporting mechanism. The motor seat 9 on the rotating mechanism is connected to the rotating seat 10 through a bearing 17, so that the rotating seat 10 can rotate on the top of the motor seat 9. The explosion-proof motor 15 provides power for the rotation of the rotating seat 10. When the explosion-proof motor 15 is started, it drives the rotating seat 10 to rotate on the top of the electrode seat through the bearing 17, thereby driving the carrier body 8 to rotate 360 ​​degrees, which is convenient for adjusting the direction of the carrier body 8.

[0036] In this embodiment, the support mechanism preferably includes a second electric telescopic rod 11 and a support plate 12. The support plate 12 is installed below the motor base 9, and the second electric telescopic rod 11 is installed between the electrode base and the support plate 12. The diameter of the support plate 12 is larger than the diameter of the rotating base 10, thereby increasing the ground contact area of ​​the support plate 12 supporting the carrier body 8, facilitating stable driving of the carrier body 8 in adjusting the direction. The second electric telescopic rod 11 drives the carrier body 8 to rise, facilitating driving the carrier body 8 for direction adjustment through the rotating mechanism.

[0037] In a specific implementation of this embodiment, in order to ensure that the explosion-proof motor 15 can be cooled, reference Figure 6 As shown, a mounting chamber 16 is provided in the motor base 9 , and an explosion-proof motor 15 is installed in the mounting chamber 16 . A heat dissipation hole 14 extending into the mounting chamber 16 is provided at the bottom of the motor base 9 .

[0038] In a specific implementation of this embodiment, in order to ensure that the motor base 9 is stably installed on the rotating base 10, refer to Figure 6As shown, a rotation groove 13 is provided at the bottom of the rotating seat 10. The inner diameter of the rotation groove 13 is smaller than the outer diameter of the bearing 17. The bearing 17 is installed in the rotation groove 13 with an interference fit. The outer diameter of the motor seat 9 is larger than the inner diameter of the bearing 17. The bearing 17 is installed in the end of the electrode seat with an interference fit. The rotation groove 13 facilitates the installation of the bearing 17 on the rotating seat 10. During this process, the bearing 17 is pressed into the rotation groove 13 by a hydraulic press, and the motor seat 9 is inserted into the bearing 17 by the hydraulic press. During the insertion process, the output end of the explosion-proof motor 15 is inserted into the rotating seat 10. The rotating seat 10 is provided with a socket that rotates with the output end, but the socket is not shown in the figure.

[0039] In a specific implementation of this embodiment, in order to ensure the carrying capacity of the carrier body 8, reference is made to Figure 2-3 As shown, a plurality of reinforcing ribs 7 are welded between the bottom of the carrier body 8 and the rotating base 10. The plurality of reinforcing ribs 7 are radially distributed outside the rotating base 10. The reinforcing ribs 7 strengthen the bearing capacity of the carrier body 8 and prevent deformation of the carrier body 8.

[0040] Example 2

[0041] refer to Figure 2 As shown, the small scale steel structure load-bearing device provided in this embodiment includes a load-bearing device body 8 and a rotating mechanism for driving the load-bearing device body 8 to rotate.

[0042] In this embodiment, combined with Figure 2 As shown, the carrier body 8 of this embodiment further includes at least three supporting legs 6 , a universal wheel 1 is mounted on one side of the bottom end of the supporting leg 6 , and a first electric telescopic rod 4 is mounted between the top of the universal wheel 1 and the supporting leg 6 .

[0043] In this embodiment, combined with Figure 5 As shown, a track 3 is welded to the side of the support leg 6 in the vertical direction. The cross-section of the track 3 is a T-shaped structure. A lifting block 2 that can be raised and lowered on the track 3 is installed on the top of the universal wheel 1. A lifting groove 18 is provided at one end of the lifting block 2 close to the track 3, and the track 3 is at least partially installed in the lifting groove 18.

[0044] Specifically, when the universal wheel 1 is stored using the small scale steel structure carrier provided in this embodiment, the following principles are referred to.

[0045] The carrier body 8 is supported on the ground by support legs 6. When the position of the carrier body 8 needs to be adjusted, the support mechanism is activated, driving the carrier body 8 to rise. At this time, the support legs 6 are lifted off the ground, and the first electric telescopic rod 4 is activated, driving the universal wheel 1 to descend downward along the side of the support legs 6. During this process, the lifting block 2 is raised and lowered on the track through the lifting slot 18, allowing the steering wheel to contact the ground. When the carrier body 8 rotates, the universal wheel 1 provides stable support for the carrier body 8 and assists the rotation of the carrier body 8. When the carrier body 8 stops rotating, the first electric telescopic rod 4 drives the universal wheel 1 to rise, and the support mechanism is reset, allowing the support legs 6 to support the ground and preventing the universal wheel 1 from being subjected to stress.

[0046] In addition, in this embodiment, reference is made to Figure 4 As shown, the top of the lifting block 2 is provided with a mounting slot 20 for accommodating the end of the first electric telescopic rod 4. A pressure sensor 19 is mounted in the mounting slot 20, below the first electric telescopic rod 4. One end of the first electric telescopic rod 4 can abut against the pressure sensor 19. The pressure sensor 19 is mounted between the first electric telescopic rod 4 and the lifting block 2 through the mounting slot 20. When the pressure sensor 19 is unloaded, the universal wheel 1 is suspended above the ground. When the force applied to the pressure sensor 19 is equal to the weight of the carrier body 8, the universal wheel 1 lifts the support leg 6 off the ground, facilitating the position adjustment of the carrier body 8.

[0047] In this embodiment, preferably, a mounting base 5 is welded to the side wall of the support leg 6 above the lifting block 2, and the first electric telescopic rod 4 is installed between the lifting block 2 and the mounting base 5. The first electric telescopic rod 4 is vertically mounted above the lifting block 2 via the mounting base 5, making it easier for the first electric telescopic rod 4 to drive the lifting block 2 up and down.
